A database TachikawaType is a type specimen database based on Dr. Tachikawa's parasitic wasp type collection donated to the Entomological Laboratory, Kyushu University. Dr. Tachikawa assisted Prof. Keizo Yasumatsu of the Entomological Laboratory of Kyushu University, who succeeded using Anicetus beneficus for biological control in Japan for the first time. He studied parasitic wasps, especially the taxonomy of the family Encyrtidae and published a revision of the family in Japan in 1963.
The number of type specimens is 463 in total, containing the holotypes described by himself and paratypes described by other researchers. Each record consists of 28 items according to the format of the Darwin Core of the Global Biodiversity Information Facility(GBIF), such as scientific name, country, type locality, collection date, collector, host, bibliographical data, etc.

The related bee database file is as follows:

Image database TOBIKOBACHI based on the encyrtid wasp collection of Dr. T. Tachikawa.

Specimen database ProctELKU based on the parasitic wasp collection of ELKU.

TachikawaType is managed by the text database management system SIGMA.

The TachikawaType file is supported by two Grants-in-Aid for Publication of Scientific Research Results (Head Investigator: M. Ito and O. Tadauchi) from the Japan Society for the Promotion of Science.

The use of data in this database is free of charge if the objective is academic study or educational purposes.
